AbstractThe Babcock solar dynamo model and known interactions of the interplanetary magnetic field with the earth''s magnetosphere are used to explain the relations found between geomagnetic indices at solar minimum and the sunspot number at the following solar maximum.
AbstractA test specimen to define the interlaminar shear strength of cloth-reinforced composite materials is developed. The specimen is a hollow circular cylinder which is subjected to torsion.
We measured CO₂ production and water flux using doubly labeled water in wild Anna''s hummingbirds living in the Santa Ana Mountains of Southern California during autumn (September) of 1981. The estimated field metabolic rate (FMR) of a hummingbird maintaining a constant body mass (mean 4.
